Problem with InvocationTargetException error

So I'm using the company standard struts framework and I've created an external class that is going to implement httpunit to perform some quick web automation. This external class is called in action class like such

webscrape ws =new webscrape(frm,"http://www.google.com");

ws.doScrape();

and the class itself looks like:

import junit.framework.*;

import com.telus.acrportal.actionform.ACRForm;

import com.meterware.httpunit.*;

import java.util.*;

publicclass webscrapeextends TestCase{

String sms_url;

ACRForm sms_frm;

public webscrape(ACRForm sms_frm,String sms_url ){

this.sms_url = sms_url;

this.sms_frm = sms_frm;

}

publicvoid doScrape ()throws Exception{

WebConversation wc =new WebConversation();

//WebResponse resp = wc.getResponse( "http://nna.tsl.telus.com/event/admin/event_send.asp" );

WebResponse resp = wc.getResponse("http://www.google.com" );

WebForm form = resp.getForms()[0];

form.setParameter("q","Disney");

form.submit();

}

and finally the error looks like this:
